This simple 315MHz receiver works with our 2 Button or 4 Button 315MHz KeyFob remotes and makes adding wireless control to an electronics project as easy as possible! These work as a simple point to point transmitter, so no microcontroller is required. We carry three different types of receiver; this version is a Toggle receiver, which acts like an alternating toggle switch – when the A button is pressed the first time, the matching pin goes high. When the A button is pressed a second time, the matching pin goes low. The pins are turned on and off by repeated presses. The receiver has 4 outputs; each button will react with its corresponding pin. Under ideal conditions we have seen this work up to 100 meters range!
